The Alzheimer's Association International Conference held its sixth Satellite Symposium in Sydney, Australia in 2019, highlighting the leadership of Australian researchers in advancing the understanding of and treatment developments for Alzheimer's disease (AD) and other dementias. This leadership includes the Australian Imaging, Biomarker, and Lifestyle Flagship Study of Ageing (AIBL), which has fueled the identification and development of many biomarkers and novel therapeutics. Two multimodal lifestyle intervention studies have been launched in Australia; and Australian researchers have played leadership roles in other global studies in diverse populations. Australian researchers have also played an instrumental role in efforts to understand mechanisms underlying vascular contributions to cognitive impairment and dementia; and through the Women's Healthy Aging Project have elucidated hormonal and other factors that contribute to the increased risk of AD in women. Alleviating the behavioral and psychological symptoms of dementia has also been a strong research and clinical focus in Australia.

Vaginal microbiota modifications from eubiosis to dysbiosis (desquamative inflammatory vaginitis, “aerobic vaginitis”) and pathobiosis have recently been demonstrated to have a pivotal role in women’s clinical health. Bacterial vaginosis (BV) and its related women’s pathology seem to be “the most common vaginal infections” in women; the Center for Disease Control (CDC) recommended treatment for this pathology: metronidazole, clyndamicin or other well known treatment such as dequalinium chloride, unfortunately, has been demonstrated to fail in control of this infection and especially in its recurrence rates. A long-lasting vaginal approach with a symbiotic drug (Lactobacillus rhamnosus BMX 54 + lactose) (NORMOGIN™) has demonstrated on a large sample of women enrolled in clinical trials (more than 3000 patients) not only to be able to significantly reduce the BV recurrences, after the CDC standard of care administration, but also to control the vaginal pathobiosis pathway, restoring the physiological eubiosis from dysbiosis. These results are really very encouraging and clearly demonstrate that a symbiotic long-lasting vaginal application of a selected Lactobacillus population plus a prebiotic could be helpful if added to the recommended standard of care.Keywords: bacterial vaginosis, Lactobacillus rhamnosus BMX 54, pathobiosis pathway

The complex multifactorial nature of polygenic Alzheimer's disease (AD) presents significant challenges for drug development. AD pathophysiology is progressing in a non-linear dynamic fashion across multiple systems levels - from molecules to organ systems - and through adaptation, to compensation, and decompensation to systems failure. Adaptation and compensation maintain homeostasis: a dynamic equilibrium resulting from the dynamic non-linear interaction between genome, epigenome, and environment. An individual vulnerability to stressors exists on the basis of individual triggers, drivers, and thresholds accounting for the initiation and failure of adaptive and compensatory responses. Consequently, the distinct pattern of AD pathophysiology in space and time must be investigated on the basis of the individual biological makeup. This requires the implementation of systems biology and neurophysiology to facilitate Precision Medicine (PM) and Precision Pharmacology (PP). The regulation of several processes at multiple levels of complexity from gene expression to cellular cycle to tissue repair and system-wide network activation has different time delays (temporal scale) according to the affected systems (spatial scale). The initial failure might originate and occur at every level potentially affecting the whole dynamic interrelated systems within an organism. Unraveling the spatial and temporal dynamics of non-linear pathophysiological mechanisms across the continuum of hierarchical self-organized systems levels and from systems homeostasis to systems failure is key to understand AD. Measuring and, possibly, controlling space- and time-scaled adaptive and compensatory responses occurring during AD will represent a crucial step to achieve the capacity to substantially modify the disease course and progression at the best suitable timepoints, thus counteracting disrupting critical pathophysiological inputs. This approach will provide the conceptual basis for effective
